Q.  Is C regex useful?

A.  Not really.

It doesn't work nicely for me and it crashes sometimes on Linux.
If the format is described (without examples!) in the re_format man page.
https://www.freebsd.org/cgi/man.cgi?query=re_format&section=7

Here's an example that appears to work

Some Alternatives:

The PCRE (Perl Compatible) library

The C++ standard library has regex stuff.
